Stop cluttering your disk space with meaningless copies of files. With just one click, Duplicate Finder finds all duplicate files on your hard disk. It quickly scans your disk and clearly presents all the duplicates so you can selectively choose which to delete.
A newly added feature, "Photo Clean", helps you clean duplicate photos in the Photos Library!
Duplicate Finder is brought to you by the same team that created Dr. Cleaner. It features an easy-to-use drag and drop user interface and includes the following functions to keep your disk clean and organized:
• Thorough and selective scan — utilizes a fast and accurate scanning technique that scans your entire Mac. You can choose to scan your entire home folder or some specific folder(s).
• Smart and accurate selection — duplicate files are selected not only by file names, but also by their contents. Files are shown in detailed previews. You can also choose the "Auto Select" feature that recommends which copy to delete.
• Easy and safe decision — duplicates can be sorted by file type and listed with their full path for you to track to the original location. You can decide if they should be sent to Trash or permanently deleted.

Does what is claims to do well…
The interface is clean and the app does exactly what it claims to do: identify duplicate files. Which, if you’re using a computer (laptop) with a smaller internal drive is theoretically awesome. If that’s your need, I honestly doubt there is a better app for it (although there may be some that are just as good).
However, the obvious “but…” here is that you’ll need to manually go through all of those duplicates and decide which ones to keep and throw away. This is much better than having it automatically do it for you and making mistakes, but it’s more time consuming than I’m willing to devote to this task.
From a developer perspective, I can’t think of any way to make this product better without some kind of AI that comes up with a clever scheme for reorganizing files based on use, although it could be that as a first panel in the clean-up process, if the app identified duplicate folders and large files, it would make freeing up space easier than the current method of showing all duplicates found.
Good tool for finding dupes
This is a great tool for finding duplicate files, even if the filenames are different. With over 50,000 image and movie files to consolidate from several backup disks, I needed help organizing the task, and this app did the job, well enough. Initial scans can be slow depending on the density of the analyzed files, but subsequent scans of the same folders is significantly faster. Stopping and restarting a scan is simple, even if you are in the middle of organizing your files. The preferences give you enough flexibility to manage the scanning target by folder location and filename, but I would add file type (‘kind’) as well to provide a wildcard option to narrow the scan search. The option to remove a file to a folder other than the Trash would also be helpful. Lastly, the interface could display a plan of action and time estimate after the first pass, allowing the user to alter the parameters in order to improve performance or reduce the processing time through changes in folder and file selection.
I understand that duplicates are difficult to nail down exactly (IE copying files might change the date tag etc), but I was expecting better performance than what I got with this app. I had a couple of folders from old computers that I used that I consolidated. I didn’t organize very well over the years and I know there are a ton of duplciate files and I didn’t expect to find every single duplciate, but I was really hoping to get better than what I got - the app found zero duplicates. I would guess because of transporting the files to and from drives maybe it changed the creation date or a couple of bits on the file. I guess I might have a unique use case, but I was hopign for a little better than this. It found zero duplicates. Maybe the app developer could add some flexibility to the app - IE tag files that are 80% the same with the same filename as a potential duplicate or something like that - that would help me out a ton!
With Family Sharing set up, up to six family members can use this app.
